I have a small ISAPI filter that needs to be finished, re-compiled and tested.
It's supposed to be already 90% done. So just small changes need to be done, but the filter needs to be tested on IIS6 for the beginning and maybe IIS 7/7.5 later on.
The filter checks downloads against url patterns, checks the referrer and for positives matches it sends a server-to-server call with a XML via POST to another server. This functionality is supposed to be finished. There's a small cookie logic missing. (more details will follow once accepted)
And the filter needs to be checked against memory leaks, etc.
Please only bid if you've developed ISAPI filters in the past.
